I haven't run the T3 but I do run the T2 on my 14.5 pinned mid length with Spike's FA BCG. It also runs a pinned Spike's Dynacomp brake. It is soooooo smooth and has almost zero muzzle rise. It's a combo that works really well together. But yes, it is a bit concussive to those around me and you better beef up your ear pro!
